Rigid Tapping

[JIMMY]

I just bought a new makino s33. I have never done rigid tapping before and I need to learn. I program in mastercam and I am wondering if there is anything special I need to do in programming. Do I program the tapping the same and change my post to put out the the right code?

Thanks in advance

Jimmy,
it is all in the output of the post, If you need help let me know

Jimmy if you have any troubles give me a call in the office. we will take care of it.

programming is the same (i use mastercam also) rigid tapping is in the machine

make sure you keep your speed and feed at 100%...

my machine won't adjust the settings, i've busted taps by not having both at 100%

the spindle down feed is syncronized with the spindle rpm...

this format works on our Makinos

G8P0 ( TURN OFF HIGH SPEED MACHINING )
S------- ( SETS RPM )
M135 ( ACTIVATE RIGID TAP MODE )
G98G84X----Y----Z----R---F---( F= IPM)
HOLE POSITIONS
G80
G8P1 ( RESUME HIGH SPEED MACHINING )

Your feed rate should be in sync with spindle rpm

Your MC post can be modified to generate this

is not a tapping head the only way to be sure it tap the part correctly? I am trying to learn tapping operations also but am a bit afraid of just putting a tap straight into a collect.

[Uncle Buck]

by using a tapping head (compression and retraction only), it will allow for minor fluctuations in depth only... this is the safe way of doing it...

by using a torque controlled tapping head with compression and retraction... if the clutch/torque slips... you will loose the spindle syncronization with the tap... this is bad, and you'll probably break the tap...
biltz type tapping heads/collets are your best bet... i just switch it from the radial drill to the cnc... i only use the direct drive collets on the CNC and the torque controlled collets on the Radial drill

[Rich05]

that is good news was considering a $600 tapping head.. can you give me a link to one of these tools.

We have a 1998 Hitachi-Seiki CNC Lathe that I haven't run in years. I have now been asked to pick it up to teach someone else how to run it. I am trying to figure out how to program a tapping procedure for a holle on the center of a part. I have a tapmatic floating rigid tap tool but can't remember how I programmed the tapping cycle. I don't recall using a special G-Code to rigid tap. Basically it was just feed in the same feedrate as your tap pitch, stop the spindle, reverse the spinde and feed out. Does anyone have a program that I could use? Our programming software does not include a rigid tapping cycle.

Thanks,
